Module 10.4, acknowledgements. This is the time to thank all the people involved in producing this class. And there is a large number of people as we will see. So, the operation of the class was led by Pedro Pinto and Juri Ranieri And you have met probably Juri Ranieri on the forum at multiple times. All the materials that was shown was reviewed by people in the lab. Jay Unnikrishnan who is a post-doc, and undergrad students Youssef, Taher and Solene went through the material before it was put online. So they are thanked for having caught a lot of bugs that were corrected and a few bugs that were still living there. The recording and editing was done by Jeremy Rieder and Tao Lee. Very important to get the quality levels that you have seen. A lot of hard work and sometimes thankless work. Don't thank you very much. The numerical examples that were put online were doing by Andrea Ridolfi and Lionel Coulot, and I hope you enjoyed them if you tried them, of course. The homework sets took a lot of effort and I know they will also created lot of effort on your side and we see here whole list of peoples have contributed homework. So Juri, Yann, Ivan, Zhoe, Reza, Feng, Mihailo, Mitra, Dirk, Andreas, Alireza, Marta and Zichong, thank you very much. It is a very challenging task to make homework that's actually for the interactive platforms that we are using. Much more so than doing homework for a class on campus. And so we also learn around a way how to try to do it correctly and we thank the audience for having been patient with us on this. And again, thank you very much for the members of the lab for having produced these homework sets. Last but not least, Jacqueline Aeberhard, who is the administrative assistant of the lab, has made everything smooth and working and she thanked very much here by everybody in the team. And last, but not least, I would like to thank Ecole Polytechnic FĂŠdĂŠrale de Lausanne for having provided some funding to be able to run this class. Thank you very much.
